摘要： PROBLEM TO BE SOLVED: To provide means for increasing the amount of a magnetic flux with minimum power consumption and maximum efficiency in a residual magnetic field type electromagnetic flowmeter.
SOLUTION: To achieve desired magnetic flux density, a magnetic circuit is made to be a parallel structure divided into N to be accommodated on a pair of core plates as a group of N exciting coils. A load of a coercive force value driven by one magnetic circuit is thereby reduced to be 1/N, reducing the consumption of exciting electric power for one magnetic circuit to be the square of (1/N). The sum total of the magnetic flux obtained by driving the N magnetic circuits in parallel is compiled on a single core plate.

摘要： PROBLEM TO BE SOLVED: To provide a capacitative electromagnetic flowmeter which is highly reliable, superior in moisture resistance and is vibration proof, suppressing eddy currents generated in an excitation magnetic path, as much as possible.
SOLUTION: The capacitative electromagnetic flowmeter is excited by a frequency which is higher than the commercial frequency and is equipped with a characteristics correction filter 8B, which corrects the gain frequency characteristic of the excitation current so as to have a flat part in the exciting magnetic flux wave form. In a detection unit 10, the electrostatic capacitance value between face electrodes 4A,4B and guard electrodes 5A, 5B is made smaller than the electrostatic capacitance value between detecting face electrodes 4A, 4B and a fluid 2 to be measured. The exciting coils 3A, 3B are fixed to a cylindrical yoke, being shielded electrostatically by coil fixing plates 9A, 9B. Fixing by grounding rings 1A1, 1A2 is performed with the cylindrical yoke and the two ends of a measurement tube 1 which is symmetrical with respect to the tube axis and to the electrode axes. In addition, fixing is effected by filling the entire interior of the detection unit 10 with epoxy resin.
